The International Labour Organization (ILO), a tripartite specialized agency of the United Nations that sets international standards related to work, has 187 member states, as of August 2022. Established in 1919 as a result of the Treaty of Versailles, the ILO was the first agency to be incorporated into the UN in 1946, is the third oldest pre-existing UN agency, the fourth oldest existing multilateral organization and the only remaining organization with direct links to the League of Nations.

Starting with 42 member states, 29 of these are considered founder members as signatories to the Versailles Treaty, another 13 states, not signatories, were invited to be members and granted status as founder members.

Following the Second World War and the dissolution of the League of Nations, the ILO became the UN's first specialized agency. All but one of the ILO's member states (the Cook Islands) are also member states of the United Nations. However, there are seven UN member states which have not joined the ILO. The ILO's constitution allows admission without membership in the UN, but the conditions to be satisfied in this case are more complex than for a UN member state.

Since establishment, 19 states have withdrawn from membership, although all subsequently rejoined. Two states have indicated an intention to withdraw, but did not complete the process. While the membership rules admit only sovereign states, on three occasions states with non-sovereign status have been admitted, all, however, eventually became sovereign members. Five states have been removed from membership, with all being readmitted. Six formerly-existing states have been members of the ILO, including two which were founding members.

Membership in the ILO is governed by Article 1, clauses 3 and 4, of the organization's constitution. Clause 3 indicates that any UN member state may become a member of the ILO by communicating to the Director-General "formal acceptance of the obligations of the Constitution." Clause 4 allows for membership for non-UN states, but this requires a two-thirds vote by delegates to the International Labour Conference, including two-thirds of government delegates.

A "+" and a blue background indicates a founding member; an "_*" and a khaki background indicates states invited to be founding members.

According to the ILO's constitution, a member state may only withdraw after giving notice of two years and settling all outstanding financial dues; following withdrawal a former member state is still obliged to comply with the ILO conventions the country has ratified.

Readmission of a former member state, that has remained a UN member, requires formal communication to the ILO Director-General of acceptance of the obligations of the ILO constitution. A former member state that is not a UN member can only be approved for readmission by a decision of the International Labour Conference.

Since 1927, 19 member states have withdrawn from the ILO; all subsequently rejoined.

Member states that have withdrawn from the International Labour Organization

Flag	State	Date of withdrawal	Date of admission	Notes
	Albania	5 August 1967	22 May 1991	In 1965, Albania gave notification of withdrawal from the ILO, citing the organization's lack of support to anti-colonial liberation movements and exclusion of communist countries. Following the end of the Cold War, Albania was admitted.
	Costa Rica	1 January 1927	21 April 1944	In December 1924, Costa Rica gave notice of withdrawal from the League of Nations due to perceived ill-treatment for overdue membership contributions and dissatisfaction with the League's lack of action against the United States for pursuing the Monroe Doctrine. Withdrawal from the League precipitated Costa Rica's withdrawal from the ILO. Starting in 1942, engagement with the ILO led to admission in 1944.
	El Salvador	1939	21 June 1948	In 1937, the government gave notice of withdrawal from the League of Nations and the ILO. The official reason given related to financial priorities, but there was also a lack of active participation by El Salvador in Geneva. Furthermore, from the mid-1930 El Salvador was more focussed on continental (Inter-American) affairs and the consequences of the failure of the League of Nations to adequately manage the Abyssinia Crisis also influenced the government's decision. Following the Second World War, El Salvador reestablished relations with the ILO and was admitted in June 1948.
	Germany	21 October 1935	12 June 1951	The passage of the Enabling Act of 1933 effectively gave the Nazi Party complete control of the German state, whereupon repression of political enemies occurred; this included trade unions, whose assets were confiscated and whose members were transferred to the Nazi-controlled German Labour Front (DAF). At the 1933 International Labour Conference the credentials of the DAF as a legitimate (independent) workers' organization were rejected and during the Conference itself, criticisms were leveled at the Nazi government's suppression of trade unions and support for antisemitism. Following the Conference, Germany gave notice of intent to withdraw from the ILO, which came into effect in 1935. After the Second World War, the Federal Republic of Germany (West Germany at the time) was admitted in 1951. The German Democratic Republic (East Germany) was admitted as a separate state from 1 January 1974.
	Guatemala	26 May 1938	19 October 1945	During the 1930s, the government increasingly focussed on continental (i.e. Inter-American) affairs which were regarded ultimately as incompatible with the League of Nations, giving notice to withdraw from the League and the ILO in May 1936. Following the Second World War, on 14 September 1945, Guillermo Toriello, Minister for External Affairs, requested admission to the ILO, which was completed the following month.
	Italy	December 1939	19 October 1945	Following the Abyssinia Crisis in 1935, where Fascist Italy ultimately annexed Ethiopia to create Italian East Africa, the government became increasingly dissatisfied with the League of Nations and on 11 December 1937, Prime Minister Benito Mussolini, in a national address, announced Italy's withdrawal from the League of Nations. On 16 December 1937, the ILO received notification from Galeazzo Ciano, Minister of Foreign Affairs, of Italy's intention to withdraw. The fall of the fascist regime led to the reestablishment of relations with the ILO in 1944, an agreement in May 1945 to appoint an ILO representative in Rome and the country's admission in October of that year.
	Honduras	10 July 1938	1 January 1955	Close to the position of Guatemala favouring Inter-American approaches, Honduras gave notification of withdrawal from the League of Nations in July 1936 and did not indicate any intention to remain in the ILO. In January 1955 Honduras was admitted.
	Japan	November 1940	26 November 1951	Starting with the Mukden Incident, Japan came under increasing criticism and condemnation in the League of Nations, eventually leading to withdrawal from the League in 1933. Although maintaining ILO membership, contradictions between government policy, a reversal of positive attitudes of the employers and the broader international deterioration of inter-state relations led to Japan giving notice of withdrawal in November 1938. Following the Second World War, in March 1948 an ILO Committee in Japan was established and in 1951 the country was admitted.
	Lesotho	15 July 1971	2 June 1980	Between 1971 and 1980, Lesotho withdrew from the ILO due to an inability to meet the financial obligations of membership.
	Nicaragua	26 June 1938	9 April 1957	Close to the position of Guatemala favouring Inter-American approaches, Nicaragua gave notice of withdrawal from the League of Nations in June 1936 and confirmed withdrawal from the ILO in June 1938. In April 1957, Nicaragua was admitted.
	Paraguay	23 February 1937	5 September 1956	Following dissatisfaction with decisions of the League of Nations related to the Chaco War, Paraguay announced withdrawal from the League and the ILO in February 1935. In September 1956, Paraguay was admitted to the ILO.
	Romania	10 July 1942	11 May 1956	Romania gave notification of withdrawal from the League of Nations in July 1940 and did not indicate any intention to remain in the ILO. In May 1956, Romania was admitted to the ILO.
	Spain	8 May 1941	28 May 1956	Spain gave notification of withdrawal from the League of Nations in May 1939 and did not indicate any intention to remain in the ILO. In May 1956, Spain was admitted to the ILO.
	Soviet Union	February 1940	26 April 1954	The Soviet Union was expelled from the League of Nations in December 1939 following the start of the Winter War. However, this expulsion did not automatically invalidate membership in the ILO; not until the meeting of the ILO Administrative Council in February the following year was the membership rescinded. While the death of leader Joseph Stalin played a direct role in the reorientation of Soviet policy, an inability to successfully influence UN affairs and a desire to have broader contacts with the non-communist world, saw the USSR take up membership in the ILO in April 1954.
	South Africa	11 March 1966	26 May 1994	In March 1964, the South African foreign minister notified the ILO of the country's withdrawal. From the late 1950s, the country's policy of institutionalized racial discrimination, officially known as Apartheid, had come under frequent condemnation; rather than be formally excluded from the ILO by a vote of the constituents, South Africa chose to withdraw. Following the end of Apartheid and the conclusion of multi-racial elections, South Africa joined the ILO in 1994.
	United States of America	6 November 1977	18 February 1980	Although US employers and trade unions had long expressed dissatisfaction with the ILO due to the admission of the Soviet Union in 1954, official United States government withdrawal was triggered by reactions to three issues in the 1970s: the role of the Soviet Union, policy towards Israel/Palestine and organizational processes. In July 1970, the appointment of the Soviet diplomat Pavel Astapenko as ILO Assistant Director-General led to the US cancelling part of its membership payments, following lobbying of the US Congress by George Meany, AFL-CIO President, who considered the ILO to be overly influenced by the Soviet Union. The adoption by the 1974 International Labour Conference of a resolution condemning "Israeli authorities" for "discrimination, racism and violation of trade union freedoms and rights" in Palestine, despite the ILO having conducted no previous investigations of matter, was strongly opposed by US representatives and the granting of observer status to the Palestine Liberation Organization (PLO) at the 1975 Conference, led the US employer, government and trade union representatives to boycott the Conference's remaining sessions. The combination of these saw the US Government give notice of an intention to withdraw in November 1975. Secretary of State Henry Kissinger indicated that the US would not follow through with withdrawal if there were improvements in US areas of concern. However, in the two years following, decisions at the ILO went against US wishes, in particular, the 1977 Conference decision which, due to a lack of quorum, failed to adopt the recommendations of the Committee of Experts (which detailed the failure to observe ILO standards in Argentina, Bolivia, Chad, Chile, Czechoslovakia, Ethiopia, Liberia and the USSR). In November 1977, President Jimmy Carter affirmed the decision of the Ford administration to withdraw from the ILO, despite advice from Secretary of State Cyrus Vance and National Security Advisor Zbigniew Brzezinski to suspend withdrawal for a year, and appeals to remain from nine West European countries, Japan and the Pope. In the years immediately following departure, changes in ILO procedures, including the introduction of secret balloting, the requirement for due process investigations prior to the adoption of resolutions and the opening of investigations into the violation of trade union rights in the Soviet Union and Poland, led to a re-evaluation, with President Carter affirming ILO membership on 18 February 1980.
	Venezuela	3 May 1957	15 March 1958	In April 1955, the Venezuelan government expelled a Dutch worker delegate of the ILO Governing Body who voiced criticisms of freedom of association rights in the country during a meeting of the ILO's Petroleum Committee in Caracas. Officers of the Governing Body subsequently adjourned the meeting, to which the Venezuelan government immediately objected and shortly after notified their intention to withdraw from the ILO. On 15 March 1958, Venezuela formally accepted the obligations of membership and was admitted.
	Vietnam	1 June 1985	20 May 1992	In June 1983, Vietnam gave notification of an intention to withdraw temporarily. The reasons included an inability to pay the assessed membership fees due to extreme financial constraints, a lack of technical support and dissatisfaction with ILO investigations into claims of Vietnamese workers being subject to forced labour in the Soviet Union. The withdrawal went into effect in 1985; Vietnam was admitted in 1992.
	Yugoslavia	16 June 1949	16 May 1951	In 1947, with the emergence of the Cold War, Yugoslavia gave notice of withdrawal, citing incompatibility between the structures of the ILO and the country's ongoing socialist development. The withdrawal came into effect in 1949, however, Yugoslavia was admitted in 1951.

Two member states have officially communicated an intention to withdraw, but prior to the ILO declaring their membership to have lapsed, subsequently communicated an intention to remain.

Member states which did not complete withdrawal from the International Labour Organization

Flag	State	Date intention to withdraw received	Date intention to withdraw rescinded	Notes
	Indonesia	25 March 1965	6 September 1966	During the period of Konfrontasi, Indonesia, under President Sukarno, came into conflict with Malaysia, Britain and the United States following Malaysia obtaining a seat in the Security Council and in January 1965, withdrawal from the United Nations was announced. In March, the government communicated an intention to withdraw from the ILO, which would have taken effect on 25 March 1967. Following the transition to the New Order, the government under President Suharto, indicated in 1966 that Indonesia no longer wished to withdraw. The ILO considered that there had been no interruption to Indonesia's membership.
	Poland	17 November 1984	17 November 1987	Following the imposition of martial law and the suppression of the independent trade union Solidarność in December 1981, the ILO governing body in May 1983 voted to constitute a commission of inquiry, the highest action which can be taken against a member state under the organization's constitution. The day after the commission's report was submitted to the ILO Governing body, which was heavily critical of the detention of trade unionists and the denial of trade union independence, Poland communicated an intention to withdraw on 17 November 1984. Poland extended that intention in November 1986 without officially withdrawing, however, with the subsequent thawing of the political situation, Poland rescinded the intention to withdraw on 17 November 1987.

Due to circumstances related to annexation, five states have been removed from ILO membership; all were later readmitted.

	Austria	13 March 1938	24 June 1947	Following the Anschluss on 12 March 1938, Austria was removed from membership of the ILO. In July 1947 the International Labour Conference confirmed Austria's readmission to the ILO.
	Ethiopia	1939	1943	Following the annexation of Ethiopia by Italy, the country was removed from the membership list of the ILO between 1939 and 1942, however, the country is still considered to have held membership since first joining on 28 September 1923.
	Estonia	1946	13 January 1992	In August 1940 the Baltic states were occupied and subsequently annexed as new republics of the Soviet Union. This action effectively terminated the Baltic states' membership, with the ILO considering this termination "definitive" in 1946. Following the declarations of independence by the Baltic states in the northern spring of 1990, the ILO indicated that an admission process was required, although this was acknowledged as readmission.
	Latvia	1946	3 December 1991
	Lithuania	1946	4 October 1991

The ILO constitution indicates that members must be states (initially, although not exclusively, members of the League of Nations or, after 1945, members of the United Nations), which has been interpreted to imply those entities with state sovereignty. The basis for this was the 26 August 1930 ruling of the Permanent Court of International Justice which determined that Danzig, whose external relations were under Poland's control, was inadmissible to the ILO. Despite this ruling, three non-sovereign states, prior to achieving sovereign status, were, due to political circumstances, admitted as members of the ILO.

Former non-sovereign state members of the International Labour Organization

Flag	State	Period of non-sovereign state status	Notes
	Byelorussian Soviet Socialist Republic	28 April 1954 – 25 December 1991	During the Yalta Conference in February 1945, Soviet Premier Joseph Stalin and US President Franklin D. Roosevelt agreed that the US and the USSR would each be entitled to two extra seats in the soon to be established United Nations. The USSR nominated the Byelorussian SSR and the Ukrainian SSR to the UN, which resulted in these two non-sovereign state entities achieving ILO membership. The USA never exercised the option for extra seats at the UN. With the dissolution of the Soviet Union, Belarus and Ukraine became the successor states for the purposes of membership.
	Ukrainian Soviet Socialist Republic	12 May 1954 – 25 December 1991
	Namibia	3 October 1978 – 21 March 1990	Namibia was admitted as the 136th full member in 1978 following a request from the United Nations Council for Namibia despite not being an independent state at the time.
